Visible from space: Hawaiian vog from Kilauea volcano, on the island of Hawaii, has been erupting continuously since 1983. This image, taken by the crew of Space Shuttle Atlantis (after completing the capture of the Hubble Space Telescope), shows the volcanic plumes from Kilauea rising up from Halemau Crater and along the coastline from lava flows entering the ocean from the East rift zone. The volcanic activity has created a blanket of volcanic fog, called vog that envelops the island. (Image Courtesy NASA)
